The present invention relates to a technology of a device for simulating lower jaw activity, and more particularly, to a device for simulating lower jaw activity that is capable of performing movements including lower jaw forward and backward moving, opening and closing (pitch), tilting left and right (yaw), in place rotating (yaw), and etc., which is capable of enhancing the adaptation efficiency of the patient to the oral appliance as well as improving the occlusion efficiency.
Conventional mandible records are usually static and fixed-point recording through a wax sheet occlusion, which mode has no sensing, feedback, judgment, and coordination action, and does not represent a real functional action, but a static record made of a plaster model with an occlusion wax sheet. Nonetheless, biological function action should involve sensing, feedback, judgement, and coordination action, which in completely different from pure mechanical action.
Therefore, the prior art tends to produce a result with a large difference to the actual lower jaw motions, especially for the patients who lack tooth for many years, rendering mandibular bone variant, and mouth and face skewness, which greatly increase the difficulty in manufacturing the dental implant or the movable denture. After the manufacturing is completed, it still requires bite paper tests for several times, as well as a long-term adaptation period.
Therefore, an object of the present invention is to provide a device capable of simulating the lower jaw motions of moving forward and backward, opening and closing (pitch), tilting left and right (yaw), in place rotating (yaw), and etc., as well as coordinating with the data of the testing devices to reverse engineer for the lower jaw motions, so as to greatly improve the adaptation time of the patient to the intraoral device and enhance the occlusion efficiency.

Based on the above structure, in an actual use scenario, the head of a tester 3 is secured on a dentistry treatment chair or a specific place by means of a head holder 21. The microcomputer 20 on the head holder 21 is connected with the pressure sensor 232 and the inertia measuring unit 233 at the other side through the transmission unit 231. The device is affixed on the lower jaw dentition by means of wax sheet or other adhesive in the manner of not hindering occlusion. When the lower jaw acts based on the temporomandibular joints as the pivot points, it will link the inertia measuring unit 233. The inertia measuring unit 233 comprises a three-axis gyroscope with three-axis acceleration meter, which is capable of measuring the angular velocity and acceleration of the lower jaw in the three-dimensional space, and calculating the measured lower jaw posture change data in this way. When the upper and lower jaw teeth occluded, the pressure sensors 232 on the teeth on the left side and the right side of the lower jaw respectively generate occlusion pressure change data by means of the internal resistance changes. Then, all of the data will be analyzed and judged by the microcomputer 20, and the result will be fed back to the tester through light signals of the LEDs 22, which respectively display the strengths of the lower jaw occlusions of the two sides. Based on the settings, a green LED 22 shine for a light occlusion force, a yellow LED 22 shine for a medium occlusion force, and a red LED 22 shine for a hard occlusion force, such that the tester will be able to adjust for a proper occlusion force by him/herself based on the colors of the light signal. Therefore, it facilitates a biological cycle act of sensing, feedback, and coordination and is capable of fully recording the lower jaw postures and occlusion forces.
